By speed · Order from slowest to fastest.

1. The drift of a tectonic plate 21.9 mm/year

   Plates move about as fast as your fingernails grow, yet over millions of years they have rearranged whole continents.

2. A Komodo dragon walking 4.8 km/h

   The largest lizard alive, it has venom glands and a bite that can topple prey far larger than itself.

3. A migrating monarch butterfly 8 km/h

   Monarchs migrate thousands of kilometres to the same forests their great-grandparents left, guided by instinct alone.

4. A charging black rhinoceros 54 km/h

   A rhino's horn is made of keratin, the same material as your hair and nails, not bone.

5. A racing greyhound 76 km/h

   Greyhounds reach their top speed in just a few strides and spend much of a sprint completely airborne.

6. The speed of sound at sea level 1.2K km/h

   Sound travels faster in warm air than cold, so a thunderclap's timing shifts slightly with the weather.
